Bug: Application crashes on Mac after reading a notification and minimizing window

Environment:

• OS: macOS Tahoe 26.4 (25E246)

• IceCubesApp version: 2.1.3

Description

IceCubes crashes each time I get and read a new notification, after I minimize the application window. Steps to reproduce:

1. Go to Chronology view
2. Wait until a new notification appears
3. Switch to Notifications view
4. Switch back to Chronology view
5. Minimize application window
6. App crashes after a few seconds.

I cloned the repo and ran the app in Xcode, and it seems to be related to a missing SceneDelegate instance in a view's environment: "SwiftUICore/Environment+Objects.swift:34: Fatal error: No Observable object of type SceneDelegate found. A View.environmentObject(_:) for SceneDelegate may be missing as an ancestor of this view."

Asked Claude to suggest a fix but to be honest my experience in swift/swiftUI is close to zero, So I would prefer someone with better understanding of the tech stack and code base to have a look at it.

I can provide the crash dump if needed.

Run IceCubesApp in Xcode and reproduce the Chronology-to-Notifications-to-Chronology flow before minimizing the window. Investigate the reported missing SceneDelegate environment object in the affected view; done means the app no longer crashes after reading a notification and minimizing the window.
